Preheat the oven to 400 degrees F. In a mixing bowl, toss the garlic with some of the olive oil. Season with salt and pepper. Place the garlic on a parchment lined baking sheet. Roast until golden, about 20 minutes. Remove from the oven and cool completely. In a mini-food processor, fitted with a metal blade, puree the garlic until smooth. Drizzle in enough olive oil to make the mixture spreadable. Season with salt and pepper. Cover and refrigerate until ready to use. The paste will keep for up to 1 week.
